Cycle 2 Work Schemes

Power up your commute

We work with a number of cycle scheme providers to help make the purchase of your new eBike and accessories more affordable. Cycle schemes allow you to make a tax-free purchase, saving up to 47%, by paying for the eBike and accessories out of your pre-tax salary. Better still, being a salary sacrifice scheme, the payments are taken out of your salary over an extended period (usually 12 months) meaning you get to spread the costs also!

Cycle to Work schemes can be processed by emailing us at info@fullycharged.com.

Who is this bike suitable for?

Hop on, pedal, glide – dynamic, powerful and silent. That’s how the ST3 will power you to work and beyond!

With a newly developed SYNO Drive ll motor, the ST3 delivers up to 820W of power with torque reaching 44 Nm. That means: You arrive at work quickly and calmly, neither soaked in sweat nor completely exhausted – unless, of course, you want to.

The ST3 not only makes your daily journeys fun, it also gives you an extremely safe ride. The outstanding grip of the Cycl-e ST tires from Pirelli, the specially designed LED front light with headlamp function or the Stromer brake system with four pistons at the front wheel and two pistons at the rear wheel ensure this high level of safety.

This bike is classed as a Moped due to the 28mph top speed. It can be ridden by any rider 16 or over who has either passed a CBT course or has category AM or P on their existing driver license.

About the Stromer ST3

Short chain stays, short wheelbase, low bottom bracket: all this and more makes the ST3’s frame geometry ideal for the needs of commuters and perfectly matched to the eBike’s 27.5” wheels.

Despite its comfortable running smoothness, the ST3 is therefore extremely nimble – a must in busy city traffic.

For the ST3, in addition to the Sport and Comfort frame in various sizes we have also developed two different stems (Urban and Urban Comfort) and three different handlebars.

You can freely combine these components so that you can enjoy the unique Stromer riding experience in a sitting position that is perfect for your body size.

What the expert says

‘Stromer has gone to great lengths to create a clean aesthetic for the ST3. The bike’s speedometer and touchscreen are integrated directly into the top tube, while the battery is hidden from view in the down tube. Built-in LED lights on the front and back are also nicely concealed in the ST3’s design with all wiring concealed in the frame of the bike itself.’

Electrical System

New for 2019, Stromer uses a freshly designed, hugely powerful 820W Syno Drive II Motor, which outputs 44Nm of torque.

The second big change is that the motor now runs at 48V, making the motor both accelerate and regenerate much more efficiently and powerfully. Finally, the fit and finish of the Syno-Drive has been considered from the perspective of service.

Instead of a bolt-on axle, the Syno-Drive uses a modern thru-axle for added rigidity and easy removal.

Omni Connect

Take full advantage of the digital world by downloading the Stromer OMNI app onto your smartphone. This app keeps you connected to your ST3 at all times ─ from anywhere ─ as well as offers many clever functions.
